Background
The fermentation system is widely used in industries such as biology, medicine, food, environmental protection, agriculture and the like, and long production time is often required in the aerobic fermentation production process, and a large amount of energy is consumed in the process, so that the energy consumption is reduced on the premise of not influencing the production efficiency through the improvement of the device, and the production cost can be greatly saved and the carbon emission is reduced.
At present, the oxygen source of the fermentation system mainly comes from compressed air, after the air is compressed, the compressed air is cooled by using a refrigerating type compressed air dryer, so that the water vapor in the air reaches the dew point, and is condensed into liquid water to be discharged. The air after supercooling treatment is injected into the fermentation tank after sterile filtration, so that the temperature of liquid in the tank can be reduced, the heat preservation system of the fermentation tank is forced to be started frequently, the heat preservation energy consumption of the fermentation tank is greatly increased, even the fermentation effect is not influenced by air inlet, and some fermentation systems can heat the air again before air inlet, so that the electricity cost is further increased.
Secondly, when the fermentation tank is used for aerobic fermentation, particularly fermentation at a higher temperature, in order to prevent liquid in the tank from being largely evaporated, an exhaust gas condensation reflux device is usually added at the air outlet, so that condensed water flows back into the tank to ensure the normal liquid level in the tank, and the main condensing medium in the condensation reflux device in the process is tap water or cold water subjected to cooling treatment. Such condensed water increases the cost of fermentation process water and, in addition, the cost of electricity used in cold water treatment. Therefore, in view of the two heat exchange processes, a device for coupling the heat exchange devices of the two can be designed, so that the energy-saving requirement in actual fermentation production is met.

Further, the compressed air storage tank, the compressed air pre-filter and the compressed air freeze dryer are connected in sequence.
Further, cold dry compressed air passes through a pressure reducing valve, enters a fermentation tank waste gas condenser, enters a post filter, and then enters the fermentation tank through a flowmeter. Further, the compressed air subjected to the cold drying treatment enters an exhaust gas condenser of the fermentation tank, and the exhaust gas and the inlet gas are subjected to heat exchange in the condenser to preheat the inlet gas.
Further, the fermenter off-gas condenser uses cold dry compressed air as a cooling medium instead of cold water.
Further, be connected with the relief pressure valve between freezing formula compressed air dryer and the waste gas condenser, prevent that the pressure that the spiral air guide fin in the condenser received is too big, reduce the gas leakage hidden danger, according to different fermentation cylinder models and scale, can independently adjust the gas outlet pressure of relief pressure valve.
Further, the trachea between the device switching, use chuck and auto-lock trachea buckle to connect, avoid gas pressure too big, cause junction gas leakage.
Further, the straight-tube type waste gas condenser is characterized in that cold air enters the sleeve from the bottom of the condenser, and spiral air guide fins are welded between the condensing tube and the condensing sleeve, so that the contact area of cold dry compressed air in the waste gas condenser is increased, and the heat exchange efficiency of the condenser is improved.
